WATER-FILTER.

Specification of Letters Patent.

Patented July 1'7, 1906.

Application filed April 11. 1906. Serial No. 311,123.

To all whom it may concern:

Be it known that I, CHARLES FRANKLIN HUBER, a citizen of the United States, residing at 1301 Farnam street, in the city of Omaha, in the county of Douglas and State of Nebraska, have invented a new and useful Improvement in ater-Filters, of which the following is a specification.

My invention relates to that class of waterfilters which are attached to the ordinary water-service fixtures in dwellings and other places and adapted for general and private use.

The object of my invention is to provide a water-filter simple, compact, and cheap in construction, easily attached to the waterservice fixtures, instantly separable for cleaning and for a renewal of the filter substance, and that will remove all organic substances from the water which passes through it.

The manner in which I accomplish my obj ect is described in the following specification and illustrated in the accompanying drawings, in which Figure 1 is a vertical elevation of the filter complete and ready for attachment to the water-service fixtures. Fig. 2 is a top plan view. Fig. 3 is a cross-sectional view on the line 3 8, Fig. 1. Fig. 4 is a cross-sectional view on the line 4 4, Fig. 2. Fig. 5 is a view of the filter substance and its fittings, the filter-stone being broken away to show the center rod running through it.

In the drawings, A is a casing having an open top tapered on the inside edge and pierced with four holes. On the bottom is a diminishing couplingB. Connected with the coupling B is a T-coupling C. Connected to this coupling is a supply-cock D and a draincock E, the supply-cock being adapted to be connected to the water-service fixtures and to thereby support the filter in position for use.

F is the filter proper, consisting of a porous stone. The stone, as shown, and the case in which it is insertible are cylindrical; but I do not wish to be restricted to that form, as the exterior form is amatter of taste and convenience and not essential to my improvement. Extending through the center of the stone is a water-chamber G. Through the center of this chamber is a rod H, threaded at both ends. Supported on the bottom end of this end of the stone is a gasket J, which closes that end of the waterohamber. Slipped over the other end of the rod is a top plate K, adapted to be secured and adjusted by a nut L on the rod H. Between this plate and the top of the stone is a gasket M, which is held in position on the stone by the plate K. This gasket is flanged and adapted to be compressed between the top end of the stone and the inside of the case and to thereby form a water-tight joint N. The plate K has a threaded cylindrical extension 0, diminished insize at the top P, which is pierced by several holes Q. A part R of the interior of this extension of the plate registers with and forms a continuation of the water-chamber in the stone and is reduced in size at S to conform to the exterior. Screwed onto the threaded part of the plate K is a T-coupling T, closed with a plug U at the top and supporting a nozzle V. The filter-stone and fittings attached to it are insertible and removable in and from the case for cleaning or repairs and are secured in the case by a U-shaped latch-bar W, which is insertible in the holes X in the case and which holds the filter in the case against the lifting pressure of the water which surrounds the filter-stone below the watertight joint formed by the gasket M.

When the filter is constructed as described and illustrated and is attached to the waterservice fixtures and the supply-cock D is opened, the Water enters the case through the coupling C, raises the filter by its pressure till it engages the latch-bar W, the space below and around the filter is filled with Water, which is held therein by the gasket M. As the water filters through the porous stone into the chamber Git is forced up thI ough the center part of the plate K and out through the holes Q into the coupling and out through the nozzle.

It is obvious that the casing may be made with a solid bottom and any suitable supplycock fitted directly therein or through the side near the bottom and that the fittings on the filter-stone may be modified in shape and construction. It is also apparent that the filter-stone and its fittings are revoluble in the case, and hence the nozzle may be turned in any position for use.

rod is a nut I, and between this nut and the fixtures; a drain-cock secured in said T-coupling; a filter-stone having a central chamber tlierethrough; a rod extending through the center of said chamber in said stone and threaded at both ends; a nut-plate attached to'the bottom end of saidrod; a gasket sup ported on said rod and nut-plate and attached thereby to the bottom end of said stone and thereby closing that end of the chamber therein; a flanged gasket supported on said rod and on the top end of said stone; a cylindrical plate secured on said rod and gasket and attached thereto and to said rod by a nut adjustable on said rod and plate, the cylindrical part of said-plate being adapted to constitute a continuation of the chamber in said stone and to form an outlet therefrom; a coupling connected with the cylindrical part of said plate covering the outlets therein and adapted to support a nozzle; and a nozzle connected with said coupling; said filter-stone and parts connected with and attached thereto being insertible in said case and a U-shaped latch-bar insertible insuitable holes in said case; said bar extending across said case and being adapted to prevent said'filt'er from being forced out of said case and to permit its removal therefrom substantially as described and for the pur poses specified. a
